DEFINITIONS

Allele. Allele is any of one or more alternative forms of a gene whichrelate to one trait or characteristic. In a diploid cell or organism,the two alleles of a given gene occupy corresponding loci on a pair ofhomologous chromosomes.

Alter. The utilization of up-regulation, down-regulation, or genesilencing.

Anther arrangement. The orientation of the anthers in fully openedflowers; anther arrangement can be useful as an identifying trait.Anther arrangements can range from introse (facing inward towardpistil), erect (neither inward not outward), or extrose (facing outwardaway from pistil).

Anther dotting. The presence/absence of anther dotting (colored spots onthe tips of anthers); if present, the percentage of anther dotting onthe tips of anthers in newly opened flowers is a distinguishing traitfor varieties.

Anther fertility. A measure of the amount of pollen produced on theanthers of a flower. Anther fertility can range from sterile (such as infemale parents used for hybrid seed production) to fertile (all anthersshedding).

Backcrossing. A process in which a breeder repeatedly crosses hybridprogeny back to one of the parents; for example, a first generationhybrid F₁ may be crossed with one of the parental genotypes of the F₁hybrid.

Blackleg (Leptosphaeria maculans). A fungal canker or dry rot disease ofthe actively growing crop that causes stem girdling and lodging. Inheavily infested crops, up to 100% of the stems may be infected,resulting in major yield loss. For purposes of this application,resistance to blackleg is measured using ratings of “R” (resistant),“MR” (moderately resistant), “MS” (moderately susceptible) or “S”(susceptible).

Cell. As used herein, the term cell includes a plant cell, whetherisolated, in tissue culture, or incorporated in a plant or plant part.

Cotyledon width. The cotyledons are leaf structures that form in thedeveloping seeds of canola that make up the majority of the mature seedof these species. When the seed germinates, the cotyledons are pushedout of the soil by the growing hypocotyls (segment of the seedling stembelow the cotyledons and above the root) and they unfold as the firstphotosynthetic leafs of the plant. The width of the cotyledons varies byvariety and can be classified as narrow, medium, or wide.

Elite canola line. A canola line which has been sold commercially.

Elite canola parent line. A canola line which is the parent line of acanola line which has been commercially sold.

Embryo. The embryo is the small plant contained within a mature seed.

Essentially all of the physiological and morphological characteristics.This phrase refers to a plant having essentially all of thephysiological and morphological characteristics of the recurrent parent,except for the characteristics derived from any converted trait.

Fatty Acid Methyl Ester (“FAME”) analysis. A method that allows foraccurate quantification of the fatty acids which make up complex lipidclasses.

Flower bud location. The location of the unopened flower buds relativeto the adjacent opened flowers is useful in distinguishing between thecanola species. The unopened buds are held above the most recentlyopened flowers in B. napus and they are positioned below the mostrecently opened flower buds in B. rapa.

Flowering date. This is measured by the number of days from planting tothe stage when 50% of the plants in a population have one or more openflowers. This varies from variety to variety.

Fusarium Wilt. Fusarium wilt, largely caused by Fusarium oxysporum, is adisease of canola that causes part or all of a plant to wilt, reducingyield by 30% or more on badly affected fields. For purposes of thisapplication, resistance to Fusarium wilt is measured using ratings of“R” (resistant), “MR” (moderately resistant), “MS” (moderatelysusceptible) or “S” (susceptible).

Gene silencing. Gene silencing means the interruption or suppression ofthe expression of a gene at the level of transcription or translation.

Genotype. This term refers to the genetic constitution of a cell ororganism.

Glucosinolates. A secondary metabolite of Brassicales that is organicand contains suffer and nitrogen; derived from glucose and an aminoacid. Glucosinolates are measured in micromoles (□m) of total alipathicglucosinolates per gram of air-dried oil-free meal. The level ofglucosinolates is somewhat influenced by the sulfur fertility of thesoil, but is also controlled by the genetic makeup of each variety andthus can be useful in characterizing varieties.

Growth habit. At the end of flowering, the angle relative to the groundsurface of the outermost fully expanded leaf petioles; avariety-specific trait. This trait can range from erect (very uprightalong the stem) to prostrate (almost horizontal and parallel with theground surface).

Leaf attachment to the stem. The manner in which the base of the leafblade clasps the stem. This trait is especially useful fordistinguishing between the two canola species. The base of the leafblade of the upper stem leaves of B. rapa completely clasp the stemwhereas those of the B. napus only partially clasp the stem. Those ofthe mustard species do not clasp the stem at all.

Leaf blade color. The color of the leaf blades is variety-specific andcan range from light to medium dark green to blue-green.

Leaf development of lobes. The varying degrees of development of lobeson leaves on the upper portion of the stem which are disconnected fromone another along the petiole of the leaf. The degree of lobing isvariety-specific and can range from absent (no lobes)/weak to verystrong (abundant lobes).

Leaf glaucosity. This refers to the waxiness of the leaves and ischaracteristic of specific varieties although environment can have someeffect on the degree of waxiness. This trait can range from absent (nowaxiness)/weak to very strong. The degree of waxiness can be bestdetermined by rubbing the leaf surface and noting the degree of waxpresent.

Leaf indentation of margin. The varying degrees of serration along theleaf margins on leaves on the upper portion of the stem. The degree ofserration or indentation of the leaf margins can vary from absent(smooth margin)/weak to strong (heavy saw-tooth like margin).

Leaf pubescence. The leaf pubescence is the degree of hairiness of theleaf surface and is especially useful for distinguishing between thecanola species. There are two main classes of pubescence, glabrous(smooth/not hairy) and pubescent (hairy), which mainly differentiatebetween the B. napus and B. rapa species, respectively.

Leaf surface. A measure of the surface texture of a leaf; the leafsurface can be used to distinguish between varieties. The surface can besmooth or rugose (lumpy) with varying degrees between the two extremes.

Linkage. This term refers to a phenomenon wherein alleles on the samechromosome tend to segregate together more often than expected if theirtransmission was independent.

Linkage disequilibrium. A phenomenon wherein alleles tend to remaintogether in linkage groups when segregating from parents to offspring,with a greater frequency than expected from their individualfrequencies.

Locus. A position on a genomic sequence that is usually found by a pointof reference, for example, the position of a DNA sequence that is agene, or part of a gene or intergenic region. A locus confers one ormore traits such as, for example, male sterility, herbicide tolerance,insect resistance, disease resistance, modified fatty acid metabolism,modified phytic acid metabolism, modified carbohydrate metabolism andmodified protein metabolism. The trait may be, for example, conferred bya naturally occurring gene introduced into the genome of the variety bybackcrossing, a natural or induced mutation, or a transgene introducedthrough genetic transformation techniques. A locus may comprise one ormore alleles integrated at a single chromosomal location.

Lodging resistance. This term refers to a variety's ability to remainerect. Lodging is rated on a scale of 1 to 5, wherein a score of 1indicates erect plants and a score of 5 indicates plants that are lyingon the ground.

Maturity. The maturity of a variety is measured as the number of daysbetween planting and physiological maturity. This trait is useful indistinguishing varieties relative to one another and when used in thiscontext it is referred to as “Relative Maturity”.

Oil content. Oil content is measured as a percent of the whole driedseed and is variety-specific. It can be determined using variousanalytical techniques such as nuclear magnetic resonance (NMR)spectroscopy, near-infrared (NIR) spectroscopy, and Soxhlet extraction.

Percent linolenic acid. This refers to the percent of total oil in theseed that is linolenic acid.

Percent oleic acid (OLE). OLE refers to the percent of total oil in theseed that is oleic acid.

Percentage of total fatty acids. This may be determined by extracting asample of oil from seed, producing the methyl esters of fatty acidspresent in that oil sample and analyzing the proportions of the variousfatty acids in the sample using gas chromatography. The fatty acidcomposition can also be a distinguishing characteristic of a variety.

Petal color. The petal color on the first day a flower opens can be adistinguishing characteristic for a variety. It can be white, varyingshades of yellow, or orange.

Plant. As used herein, the term “plant” includes plant cells, plantprotoplasts, plant cell tissue cultures from which canola plants can beregenerated, plant calli, plant clumps, and plant cells that are intactin plants or parts of plants, such as embryos, pollen, ovules, flowers,pods, leaves, roots, root tips, anthers, cotyledons, hypocotyls,meristematic cells, stems, pistils, petiole, and an immature or maturewhole plant, including a plant from which seed or grain or anthers havebeen removed. Seed or embryo that will produce the plant is alsoconsidered to be the plant.

Plant height. This is the height of the plant at the end of flowering ifthe floral branches are extended upright (i.e., not lodged). This variesfrom variety to variety and although it can be influenced byenvironment, relative comparisons between varieties grown side by sideare useful for variety identification.

Plant parts. As used herein, the term “plant parts” (or “canola plant,or a part thereof” or similar phrasings) includes protoplasts, leaves,stems, roots, root tips, anthers, pistils, seed, grain, embryo, pollen,ovules, cotyledon, hypocotyl, pod, flower, shoot, tissue, petiole,cells, meristematic cells and the like.

Resistance to lodging. This term refers to the ability of a variety tostand up in the field under high yield conditions and severeenvironmental factors. A variety can have very good, good (remainsupright), fair, or poor (falls over) resistance to lodging. The degreeof resistance to lodging is not expressed under all conditions but ismost meaningful when there is some degree of lodging in a field trial.

Seed coat color. The color of the seed coat can be variety-specific andcan range from black to brown to yellow. Color can also be mixed forsome varieties.

Seed coat mucilage. This refers to a gel-like substance on the seed coatthat draws water to itself. It can be useful for differentiating betweenthe two species of canola with B. rapa varieties having mucilage presentin their seed coats whereas B. napus varieties do not have this present.It is detected by imbibing seeds with water and monitoring the mucilagethat is exuded by the seed.

Seedling growth habit. This term refers to the rosette, which consistsof the first 2-8 true leaves; a variety can be characterized as having astrong rosette (closely packed leaves) or a weak rosette (looselyarranged leaves).

Silique (pod) habit. This term refers to the orientation of the podsalong the racemes (flowering stems) and is variety-specific. This traitcan range from erect (pods angled close to racemes) to horizontal (podsperpendicular to racemes) to arching (pods show distinct arching habit).

Silique (pod) length of beak. The beak is the segment at the end of thepod which does not contain seed (it is a remnant of the stigma and stylefor the flower). The length of the beak can be variety-specific and canrange from short to medium to long.

Silique (pod) length of pedicel. The pedicel is the stem that attachesthe pod to the raceme or flowering shoot. The length of the pedicel canbe variety-specific and can vary from short to medium to long.

Silique (pod) length. This is the length of the fully developed pods andcan range from short to medium to long. In characterizing a variety, itis best used by making comparisons relative to reference varieties.

Silique (pod) type. The type of pod; this is typically a bilateralsingle pod for both species of canola and is, therefore, not very usefulfor variety identification within these species.

Silique (pod) width. This is the width of a fully developed pod and canrange from narrow to medium to wide. In characterizing a variety, it isbest used by making comparisons relative to reference varieties.

Single gene converted (conversion). This term refers to plants that aredeveloped using a plant breeding technique known as backcrossing, or viagenetic engineering, wherein essentially all of the desiredmorphological and physiological characteristics of a variety arerecovered in addition to the single gene transferred into the varietyvia the backcrossing technique or via genetic engineering.

Stem intensity of anthocyanin coloration. The varying degrees of purplecoloration on stems and other organs of canola plants, which is due tothe presence of anthocyanin (purple) pigments. The degree of colorationis somewhat subject to growing conditions, but varieties typically showvarying degrees of coloration ranging from: absent (no purple) to veryweak to very strong (deep purple coloration).

A. Origin and Breeding History

SCV119103 is a conventional (non transgenic), pollen-fertile canolarestorer inbred line (R-line) used for producing hybrids with resistanceto blackleg and Fusarium wilt. Spring canola variety SCV119103 wasdeveloped from the cross of SCV378221 and SCV475099 (proprietary springcanola inbred lines of Monsanto Technology LLC). An F1 progeny selectedfrom this cross was self-pollinated and the pedigree system of plantbreeding was then used to develop SCV119103, which is an F8 levelselection. Some of the criteria used for selection in variousgenerations include: fertility, standability, disease tolerance,combining ability, oil content, maturity and total saturated fats.

Neither of the original parent lines of SCV119103 has been directlyavailable publicly or commercially as an inbred line and, therefore, nopublic or commercial designations have been used for the original parentlines. The original female parent line (SCV378221) of SCV119103 has beenused as the restorer parental component of various commercial hybridsdeveloped and owned by Monsanto Technology LLC. Another inbred line,SCV470336, was selected from the same parental cross as SCV119103 andhas been used as the parental component of a canola hybrid owned byMonsanto Technology LLC that has been commercialized. Canola lineSCV119103 is not a parent of any other canola line commercialized at thetime of the present patent filing. A patent application was submitted onFeb. 26, 2010 for SCV470336, a sib inbred line of SCV119103.

Canola line SCV119103 is stable, uniform and no off-type plants havebeen exhibited in evaluation. The line has shown uniformity andstability, as described in the following variety descriptioninformation. It has been self-pollinated a sufficient number ofgenerations with careful attention to uniformity of plant type. The linehas been increased with continued observation for uniformity.

B. Phenotypic Description

In an embodiment, the invention is directed to methods for producing acanola plant by crossing a first parent canola plant with a secondparent canola plant, wherein the first or second canola plant is thecanola plant from the line SCV119103. Further, both first and secondparent canola plants may be from the line SCV119103. Any methods usingthe line SCV119103 are part of this invention: selfing, backcrosses,hybrid breeding, and crosses to populations. Any plants produced usingline SCV119103 as a parent are within the scope of the invention.

Additional methods of the present invention include, but are not limitedto, expression vectors introduced into plant tissues using a direct genetransfer method such as microprojectile-mediated delivery, DNAinjection, and electroporation. Expression vectors may be introducedinto plant tissues by using either microprojectile-mediated deliverywith a biolistic device or by using Agrobacterium-mediatedtransformation. Transformant plants obtained with the protoplasm of theinvention are intended to be within the scope of this invention.

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies which are inserted into the genome using transformation, arereferred to herein collectively as “transgenes”. In some embodiments ofthe invention, a transgenic variant of SCV119103 may contain at leastone transgene but could contain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10transgenes and/or no more than 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4,3, or 2 transgenes. Over the last fifteen to twenty years severalmethods for producing transgenic plants have been developed, and thepresent invention also relates to transgenic variants of the claimedcanola line SCV119103.

One embodiment of the invention is a process for producing canola lineSCV119103 further comprising a desired trait, said process comprisingtransforming a canola plant of line SCV119103 with a transgene thatconfers a desired trait. Another embodiment of the invention comprises acanola plant produced by this process. In one embodiment, the desiredtrait may be one or more of herbicide tolerance, insect resistance,disease resistance, modified seed yield, modified oil percent, modifiedprotein percent, modified lodging resistance, or modified fatty acid orcarbohydrate metabolism. The specific gene may be any gene known in theart or listed herein, including but not limited to a polynucleotideconferring resistance or tolerance to imidazolinone, sulfonylurea,glyphosate, glufosinate, 2,4-D, Dicamba, L-phosphinothricin, triazine,hydroxyphenylpyruvate dioxygenase inhibitor, protoporphyrinogen oxidaseinhibitor, phenoxy proprionic acid, cyclohexone, and benzonitrile; apolynucleotide encoding a Bacillus thuringiensis polypeptide, apolynucleotide encoding phytase, fatty acid desaturase (FAD)-2, FAD-3,galactinol synthase or a raffinose synthetic enzyme; or a polynucleotideconferring resistance to blackleg, white rust or other common canoladiseases.

Numerous methods for plant transformation have been developed and areincluded as part of the invention, including biological and physicalplant transformation protocols. See, for example, Miki, et al.,“Procedures for Introducing Foreign DNA into Plants” in Methods in PlantMolecular Biology and Biotechnology, Glick, B. R. and Thompson, J. E.Eds. (CRC Press, Inc., Boca Raton, 1993) pages 67-88 and “GeneticTransformation for the Improvement of Canola”, in World Conference onBiotechnology for the Fats and Oils Industry. 1988. In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available and are includedwithin the invention. See e.g. Gruber, et al., “Vectors for PlantTransformation” in Methods in Plant Molecular Biology and Biotechnology,Glick, B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton,1993) pages 89-119.

As an embodiment of the invention, a genetic trait which has beenengineered into the genome of a particular canola plant may then bemoved into the genome of another variety using traditional breedingtechniques that are well-known in the plant breeding arts. For example,a backcrossing approach may be used to move a transgene from atransformed canola variety into an already-developed canola variety, andthe resulting backcross conversion plant would then comprise thetransgene(s).

As an embodiment of the invention, various genetic elements can beintroduced into the plant genome using transformation techniques. Theseelements include, but are not limited to genes, coding sequences,inducible, constitutive, and tissue specific promoters, enhancingsequences, and signal and targeting sequences. For example, see thetraits, genes and transformation methods listed in U.S. Pat. No.6,118,055, incorporated herein by reference in its entirety.

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of or operatively linked to a regulatoryelement (for example, a promoter). The expression vector may contain oneor more such operably linked gene/regulatory element combinations. Thevector(s) may be in the form of a plasmid, and can be used alone or incombination with other plasmids, to provide transformed canola plants,using transformation methods as described below to incorporatetransgenes into the genetic material of the canola plant(s).

Expression Vectors for Canola Transformation Marker Genes

Expression vectors include at least one genetic marker operably linkedto a regulatory element (a promoter, for example) that allowstransformed cells containing the marker to be either recovered bynegative selection, i.e., inhibiting growth of cells that do not containthe selectable marker gene, or by positive selection, i.e., screeningfor the product encoded by the genetic marker. Any selectable markerknown in the art and/or discussed herein may be used in the presentinvention. Many commonly used selectable marker genes for planttransformation are well-known in the transformation arts, and include,for example, genes that code for enzymes that metabolically detoxify aselective chemical agent which may be an antibiotic or an herbicide, orgenes that encode an altered target which is insensitive to theinhibitor. A few positive selection methods are also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley, et al., Proc. Natl. Acad. Sci. U.S.A., 80:4803 (1983). Anothercommonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen, et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase, aminoglycoside-3′-adenyl transferaseand the bleomycin resistance determinant. Hayford, et al., PlantPhysiol. 86:1216 (1988), Jones, et al., Mol. Gen. Genet., 210:86 (1987),Svab, et al., Plant Mol. Biol. 14:197 (1990) Hille, et al., Plant Mol.Biol. 7:171 (1986). Other selectable marker genes confer resistance ortolerance to herbicides such as glyphosate, glufosinate or bromoxynil.Comai, et al., Nature 317:741-744 (1985), Gordon-Kamm, et al., PlantCell 2:603-618 (1990) and Stalker, et al., Science 242:419-423 (1988).

Selectable marker genes for plant transformation not of bacterial origininclude, for example, mouse dihydrofolate reductase, plant5-enolpyruvylshikimate-3-phosphate synthase and plant acetolactatesynthase. Eichholtz, et al., Somatic Cell Mol. Genet. 13:67 (1987),Shah, et al., Science 233:478 (1986), Charest, et al., Plant Cell Rep.8:643 (1990).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells rather than directgenetic selection of transformed cells for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include □-glucuronidase (GUS),□-galactosidase, luciferase and chloramphenicol acetyltransferase.Jefferson, R. A., Plant Mol. Biol. Rep. 5:387 (1987), Teeri, et al.,EMBO J. 8:343 (1989), Koncz, et al., Proc. Natl. Acad. Sci. U.S.A.84:131 (1987), DeBlock, et al., EMBO J. 3:1681 (1984).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available. Molecular Probes publication2908, IMAGENE GREEN J., p. 1-4 (1993) and Naleway, et al., J. Cell Biol.115:151a (1991). However, these in vivo methods for visualizing GUSactivity have not proven useful for recovery of transformed cellsbecause of low sensitivity, high fluorescent backgrounds and limitationsassociated with the use of luciferase genes as selectable markers.

More recently, a gene encoding Green Fluorescent Protein (GFP) has beenutilized as a marker for gene expression in prokaryotic and eukaryoticcells. Chalfie, et al., Science 263:802 (1994). GFP and mutants of GFPmay be used as screenable markers.

Expression Vectors for Canola Transformation Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element, for example, a promoter. Anypromoter known in the art and/or discussed herein may be used in thepresent invention. Several types of promoters are now well-known in thetransformation arts, as are other regulatory elements that can be usedalone or in combination with promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred”.Promoters which initiate transcription only in certain tissues arereferred to as “tissue-specific”. A “cell type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may effect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter which is active under mostenvironmental conditions.

-   -   A. Inducible Promoters—An inducible promoter is operably linked        to a gene for expression in canola. Optionally, the inducible        promoter is operably linked to a nucleotide sequence encoding a        signal sequence which is operably linked to a gene for        expression in canola. With an inducible promoter the rate of        transcription increases in response to an inducing agent.    -   Any inducible promoter can be used in the instant invention. See        Ward, et al., Plant Mol. Biol. 22:361-366 (1993). Exemplary        inducible promoters include, but are not limited to, that from        the activating copper-metallothionein expression I (ACEI) system        which responds to copper (Mett, et al., PNAS 90:4567-4571        (1993)); In2 gene from maize which responds to        benzenesulfonamide herbicide safeners (Hershey, et al., Mol.        Gen. Genetics 227:229-237 (1991) and Gatz, et al., Mol. Gen.        Genetics 243:32-38 (1994)) or Tet repressor from Tn10 (Gatz, et        al., Mol. Gen. Genetics 227:229-237 (1991)). A particular        inducible promoter responds to an inducing agent to which plants        do not normally respond. An exemplary inducible promoter is the        inducible promoter from a steroid hormone gene, the        transcriptional activity of which is induced by a        glucocorticosteroid hormone. Schena, et al., Proc. Natl. Acad.        Sci. U.S.A. 88:0421 (1991).    -   B. Constitutive Promoters—A constitutive promoter is operably        linked to a gene for expression in canola or the constitutive        promoter is operably linked to a nucleotide sequence encoding a        signal sequence which is operably linked to a gene for        expression in canola.    -   Many different constitutive promoters can be utilized in the        instant invention. Exemplary constitutive promoters include, but        are not limited to, the promoters from plant viruses such as the        35S promoter from CaMV (Odell, et al., Nature 313:810-812        (1985)) and the promoters from such genes as rice actin        (McElroy, et al., Plant Cell 2:163-171 (1990)); ubiquitin        (Christensen, et al., Plant Mol. Biol. 12:619-632 (1989) and        Christensen, et al., Plant Mol. Biol. 18:675-689 (1992)); pEMU        (Last, et al., Theor. Appl. Genet. 81:581-588 (1991)); MAS        (Velten, et al., EMBO J. 3:2723-2730 (1984)) and maize H3        histone (Lepetit, et al., Mol. Gen. Genetics 231:276-285 (1992)        and Atanassova, et al., Plant Journal 2 (3): 291-300 (1992)).        The ALS promoter, Xba1/Nco1 fragment 5′ to the Brassica napus        ALS3 structural gene (or a nucleotide sequence similarity to        said Xba1/Nco1 fragment), represents a particularly useful        constitutive promoter. See PCT Application No. WO 96/30530,        incorporated herein by reference in its entirety.    -   C. Tissue-Specific or Tissue-Preferred Promoters—A        tissue-specific promoter is operably linked to a gene for        expression in canola. Optionally, the tissue-specific promoter        is operably linked to a nucleotide sequence encoding a signal        sequence which is operably linked to a gene for expression in        canola. Plants transformed with a gene of interest operably        linked to a tissue-specific promoter produce the protein product        of the transgene exclusively, or preferentially, in a specific        tissue.    -   Any tissue-specific or tissue-preferred promoter can be utilized        in the instant invention. Exemplary tissue-specific or        tissue-preferred promoters include, but are not limited to, a        root-preferred promoter such as that from the phaseolin gene        (Murai, et al., Science 23:476-482 (1983) and Sengupta-Gopalan,        et al., Proc. Natl. Acad. Sci. U.S.A. 82:3320-3324 (1985)); a        leaf-specific and light-induced promoter such as that from cab        or rubisco (Simpson, et al., EMBO J. 4(11):2723-2729 (1985) and        Timko, et al., Nature 318:579-582 (1985)); an anther-specific        promoter such as that from LAT52 (Twell, et al., Mol. Gen.        Genetics 217:240-245 (1989)); a pollen-specific promoter such as        that from Zm13 (Guerrero, et al., Mol. Gen. Genetics 244:161-168        (1993)) or a microspore-preferred promoter such as that from apg        (Twell, et al., Sex. Plant Reprod. 6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of protein produced by transgenes to a subcellular compartmentsuch as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall ormitochondrion or for secretion into the apoplast, is accomplished bymeans of operably linking the nucleotide sequence encoding a signalsequence to the 5′ and/or 3′ region of a gene encoding the protein ofinterest. Targeting sequences at the 5′ and/or 3′ end of the structuralgene may determine, during protein synthesis and processing, where theencoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See e.g.Becker, et al., Plant Mol. Biol. 20:49 (1992), Knox, C., et al., PlantMol. Biol. 9:3-17 (1987), Lerner, et al., Plant Physiol. 91:124-129(1989), Fontes, et al., Plant Cell 3:483-496 (1991), Matsuoka, et al.,Proc. Natl. Acad. Sci. 88:834 (1991), Gould, et al., J. Cell. Biol.108:1657 (1989), Creissen, et al., Plant J. 2:129 (1991), Kalderon, etal., Cell 39:499-509 (1984), Steifel, et al., Plant Cell 2:785-793(1990). Any signal sequence known in the art and/or discussed herein maybe used in the present invention.

Foreign Protein Genes and Agronomic Genes

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem. 114:92-6(1981).

According to an embodiment, the transgenic plant provided for commercialproduction of foreign protein is a canola plant. In another embodiment,the biomass of interest is seed. For the relatively small number oftransgenic plants that show higher levels of expression, a genetic mapcan be generated, primarily via conventional restriction fragment lengthpolymorphism (RFLP), polymerase chain reaction (PCR), short sequencerepeats (SSR) analysis, which identifies the approximate chromosomallocation of the integrated DNA molecule. For exemplary methodologies inthis regard, see Glick and Thompson, Methods in Plant Molecular Biologyand Biotechnology CRC Press, Boca Raton 269:284 (1993). Map informationconcerning chromosomal location is useful for proprietary protection ofa subject transgenic plant. If unauthorized propagation is undertakenand crosses made with other germplasm, the map of the integration regioncan be compared to similar maps for suspect plants, to determine if thelatter have a common parentage with the subject plant. Map comparisonswould involve hybridizations, RFLP, PCR, SSR and sequencing, all ofwhich are conventional techniques.

Wang, et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science,280:1077-1082, 1998, and similar capabilities are becoming increasinglyavailable for the canola genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR and sequencing, all of which areconventional techniques. Single nucleotide polymorphism (SNP)s may alsobe used alone or in combination with other techniques.

In an embodiment of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of canola the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide tolerance,agronomic, grain quality and other traits. Transformation can also beused to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to canola as well as non-native DNAsequences can be transformed into canola and used to alter levels ofnative or non-native proteins. Various promoters, targeting sequences,enhancing sequences, and other DNA sequences can be inserted into thegenome for the purpose of altering the expression of proteins. Reductionof the activity of specific genes (also known as gene silencing, or genesuppression) may also desirable for several aspects of geneticengineering in plants.

Many techniques for gene silencing are well-known to one of skill in theart, including but not limited to knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook ch.118, Springer-Verlag, 1994) or other genetic elements such as a FRT, Loxor other site specific integration site, antisense technology (see,e.g., Sheehy, et al.

Plant Bio. 2:109-113); target-RNA-specific ribozymes (Haseloff, etal. (1988) Nature 334: 585-591); hairpin structures (Smith, et al.(2000) Nature 407:319-320; WO 99/53050; and WO 98/53083), incorporatedherein by reference in their entirety; MicroRNA (Aukerman & Sakai (2003)Plant Cell 15:2730-2741); ribozymes (Steinecke, et al.

Likewise, by means of the present invention, agronomic genes can beexpressed in transformed plants. More particularly, plants can begenetically engineered to express various phenotypes of agronomicinterest. Exemplary genes implicated in this regard include, but are notlimited to, those categorized below:

1. Genes that Confer Resistance to Pests or Disease and that Encode:

Plant defenses are often        activated by specific interaction between the product of a        disease resistance gene (R) in the plant and the product of a        corresponding avirulence (Avr) gene in the pathogen. A plant        variety can be transformed with cloned resistance genes to        engineer plants that are resistant to specific pathogen strains.        See, for example Jones, et al., Science 266:789 (1994) (cloning        of the tomato Cf-9 gene for resistance to Cladosporium fulvum);        Martin, et al., Science 262:1432 (1993) (tomato Pto gene for        resistance to Pseudomonas syringae pv. tomato encodes a protein        kinase); Mindrinos, et al., Cell 78:1089 (1994) (Arabidopsis        RSP2 gene fOr resistance to Pseudomonas syringae), McDowell &        Woffenden, (2003) Trends Biotechnol. 21(4): 178-83 and Toyoda,        et al., (2002) Transgenic Res. 11 (6):567-82.    -   B.

DNA molecules which contain        chitinase-encoding sequences can be obtained, for example, from        the ATCC under Accession Nos. 39637 and 67152. See also Kramer,        et al., Insect Biochem. Molec.

For example, the accumulation of viral coat proteins        in transformed plant cells imparts resistance to viral infection        and/or disease development effected by the virus from which the        coat protein gene is derived, as well as by related viruses. See        Beachy, et al., Ann. rev. Phytopathol. 28:451 (1990).

A developmental-arrestive protein produced in nature by a        pathogen or a parasite. Thus, fungal        endo-□-1,4-D-polygalacturonases facilitate fungal colonization        and plant nutrient release by solubilizing plant cell wall        homo-□-1,4-D-galacturonase. See Lamb, et al., Bio/Technology        10:1436 (1992).

Cloning and expression of DNA coding        for a glutathione S-transferase is described by Hayes, et al.,        Biochem. J. 285:173 (1992).    -   D. Acetohydroxy acid synthase, which has been found to make        plants that express this enzyme resistant to multiple types of        herbicides, has been introduced into a variety of plants. See        Hattori, et al., Mol. Gen. Genet. 246:419, 1995. Other genes        that confer tolerance to herbicides include a gene encoding a        chimeric protein of rat cytochrome P4507A1 and yeast        NADPH-cytochrome P450 oxidoreductase (Shiota, et al., Plant        Physiol., 106:17, 1994), genes for glutathione reductase and        superoxide dismutase (Aono, et al., Plant Cell Physiol. 36:1687,        1995), and genes for various phosphotransferases (Datta, et al.,        Plant Mol.

The protox enzyme serves as the target for a variety        of herbicidal compounds. These herbicides also inhibit growth of        all the different species of plants present, causing their total        destruction. The development of plants containing altered protox        activity which are resistant to these herbicides are described        in U.S. Pat.

Genes that Confer or Contribute to a Value-Added Trait:    -   A. Modified fatty acid metabolism, for example, by transforming        a plant with an antisense gene of stearyl-ACP desaturase to        increase stearic acid content of the plant. See Knultzon, et        al., Proc. Natl. Acad. Sci. U.S.A. 89:2624 (1992).    -   B. Decreased phytate content: 1) Introduction of a        phytase-encoding gene would enhance breakdown of phytate, adding        more free phosphate to the transformed plant. For example, see        Van Hartingsveldt, et al., Gene 127:87 (1993), for a disclosure        of the nucleotide sequence of an Aspergillus niger phytase        gene. 2) A gene could be introduced that reduced phytate        content. In maize for example, this could be accomplished by        cloning and then reintroducing DNA associated with the single        allele which is responsible for maize mutants characterized by        low levels of phytic acid. See Raboy, et al., Maydica        35:383 (1990) and/or by altering inositol kinase activity as in        WO 02/059324, U.S. Pat.

See, for        example, Horsch, et al., Science 227:1229 (1985). A. tumefaciens        and A. rhizogenes are plant pathogenic soil bacteria which        genetically transform plant cells. The Ti and Ri plasmids of A.        tumefaciens and A. rhizogenes, respectively, carry genes        responsible for genetic transformation of the plant. See, for        example, Kado, C. I., Crit. Rev. Plant Sci. 10:1 (1991).        Descriptions of Agrobacterium vector systems and methods for        Agrobacterium-mediated gene transfer are provided by Gruber, et        al., supra, Miki, et al., supra, and Moloney, et al., Plant Cell        Reports 8:238 (1989). See also, U.S. Pat. No. 5,563,055        (Townsend and Thomas), incorporated herein by reference in its        entirety.    -   B. Direct Gene Transfer—Several methods of plant transformation,        collectively referred to as direct gene transfer, have been        developed as an alternative to Agrobacterium-mediated        transformation. A generally applicable method of plant        transformation is microprojectile-mediated transformation        wherein DNA is carried on the surface of microprojectiles        measuring 1 to 4 □m. The expression vector is introduced into        plant tissues with a biolistic device that accelerates the        microprojectiles to speeds of 300 to 600 m/s which is sufficient        to penetrate plant cell walls and membranes.

C., Physiol Plant 7:206 (1990), Klein, et al.,        Biotechnology 10:268 (1992). See also U.S. Pat. No. 5,015,580        (Christou, et al.) and U.S. Pat. No. 5,322,783 (Tomes, et al.),        each of which is incorporated herein by reference in its        entirety.    -   Another method for physical delivery of DNA to plants is        sonication of target cells. Zhang, et al., Bio/Technology 9:996        (1991).    -   Alternatively, liposome and spheroplast fusion have been used to        introduce expression vectors into plants. Deshayes, et al., EMBO        J., 4:2731 (1985), Christou, et al., Proc Natl. Acad. Sci.        U.S.A. 84:3962 (1987). Direct uptake of DNA into protoplasts        using CaCl₂ precipitation, polyvinyl alcohol or poly-L-ornithine        has also been reported. Hain, et al., Mol. Gen. Genet.        199:161 (1985) and Draper, et al., Plant Cell Physiol. 23:451        (1982). Electroporation of protoplasts and whole cells and        tissues have also been described. Donn, et al., In Abstracts of        VIIth International Congress on Plant Cell and Tissue Culture        IAPTC, A2-38, p 53 (1990); D'Halluin, et al., Plant Cell        4:1495-1505 (1992) and Spencer, et al., Plant Mol. Biol.        24:51-61 (1994).    -   Following transformation of canola target tissues, expression of        the above-described selectable marker genes allows for        preferential selection of transformed cells, tissues and/or        plants, using regeneration and selection methods well-known in        the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed with another (non-transformed or transformed) variety, in orderto produce a new transgenic variety. Alternatively, a genetic traitwhich has been engineered into a particular canola line using theforegoing transformation techniques could be moved into another lineusing traditional backcrossing techniques that are well-known in theplant breeding arts. For example, a backcrossing approach could be usedto move an engineered trait from a public, non-elite variety into anelite variety, or from a variety containing a foreign gene in its genomeinto a variety or varieties which do not contain that gene. As usedherein, “crossing” can refer to a simple X by Y cross, or the process ofbackcrossing, depending on the context.

Genetic Marker Profile Through SSR and First Generation Progeny

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety ora related variety or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such as RFLP,Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily PrimedPolymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting(DAF), Sequence Characterized Amplified Regions (SCARs), AmplifiedFragment Length Polymorphisms (AFLPs), SSRs which are also referred toas Microsatellites, and SNPs. For exemplary methodologies, see Glick, etal., 1993. Methods in Plant Molecular Biology and Biotechnology. CRCPress, Boca Raton.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci forSCV119103.

In addition to being used for identification of canola line SCV119103and plant parts and plant cells of line SCV119103, the genetic profilemay be used to identify a canola plant produced through the use ofSCV119103 or to verify a pedigree for progeny plants produced throughthe use of SCV119103. The genetic marker profile is also useful inbreeding and developing backcross conversions.

The present invention comprises a canola plant characterized bymolecular and physiological data obtained from the representative sampleof said variety deposited with the American Type Culture Collection(ATCC). Further provided by the invention is a canola plant formed bythe combination of the disclosed canola plant or plant cell with anothercanola plant or cell and comprising the homozygous alleles of thevariety.

Means of performing genetic marker profiles using SSR polymorphisms arewell-known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may bepresent. Another advantage of this type of marker is that, through useof flanking primers, detection of SSRs can be achieved, for example, byPCR, thereby eliminating the need for labor-intensive Southernhybridization. The PCR detection is done by use of two oligonucleotideprimers flanking the polymorphic segment of repetitive DNA. Repeatedcycles of heat denaturation of the DNA followed by annealing of theprimers to their complementary sequences at low temperatures, andextension of the annealed primers with DNA polymerase, comprise themajor part of the methodology. For example, see Batley, J., et al. 2007.Mol. Ecol. Notes (OnlineEarly Articles) and Plieske, J., et al., 2001.Theor. Appl. Genet. 102:689-694.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing varieties it is preferable if all SSRprofiles are performed in the same lab.

The SSR profile of canola plant SCV119103 can be used to identify plantscomprising SCV119103 as a parent, since such plants will comprise thesame homozygous alleles as SCV119103. Because the canola variety isessentially homozygous at all relevant loci, most loci should have onlyone type of allele present. In contrast, a genetic marker profile of anF₁ progeny should be the sum of those parents, e.g., if one parent washomozygous for allele x at a particular locus, and the other parenthomozygous for allele y at that locus, then the F₁ progeny will be xy(heterozygous) at that locus. Subsequent generations of progeny producedby selection and breeding are expected to be of genotype x (homozygous),y (homozygous), or xy (heterozygous) for that locus position. When theF₁ plant is selfed or sibbed for successive filial generations, thelocus should be either x or y for that position.

In addition, plants and plant parts substantially benefiting from theuse of SCV119103 in their development, such as SCV119103 comprising abackcross conversion, transgene, or genetic sterility factor, may beidentified by having a molecular marker profile with a high percentidentity to SCV119103. Such a percent identity might be 95%, 96%, 97%,98%, 99%, 99.5% or 99.9% identical to SCV119103.

The SSR profile of SCV119103 also can be used to identify essentiallyderived varieties and other progeny varieties developed from the use ofSCV119103, as well as cells and other plant parts thereof. Such plantsmay be developed using the markers identified in WO 00/31964, U.S. Pat.No. 6,162,967 and U.S. Pat. No. 7,288,386, each of which is incorporatedherein by reference in its entirety. Progeny plants and plant partsproduced using SCV119103 may be identified by having a molecular markerprofile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%,75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%,89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% geneticcontribution from canola variety, as measured by either percent identityor percent similarity. Such progeny may be further characterized asbeing within a pedigree distance of SCV119103, such as within 1, 2, 3,4, or 5 or less cross-pollinations to a canola plant other thanSCV119103 or a plant that has SCV119103 as a progenitor. Uniquemolecular profiles may be identified with other molecular tools such asSNPs and RFLPs.

While determining the SSR genetic marker profile of the plants describedsupra, several unique SSR profiles may also be identified which did notappear in either parent of such plant. Such unique SSR profiles mayarise during the breeding process from recombination or mutation. Acombination of several unique alleles provides a means of identifying aplant variety, an F₁ progeny produced from such variety, and progenyproduced from such variety.

Single-Gene Conversions

When the term “canola plant” is used in the context of the presentinvention, this also includes any single gene conversions of thatvariety. The term “single gene converted plant,” as used herein, refersto those canola plants which are developed by a plant breeding techniquecalled backcrossing wherein essentially all of the desired morphologicaland physiological characteristics of a variety are recovered in additionto the single gene transferred into the variety via the backcrossingtechnique. Backcrossing methods can be used with the present inventionto improve or introduce a characteristic into the variety. The term“backcrossing” as used herein refers to the repeated crossing of ahybrid progeny back to the recurrent parent, i.e., backcrossing 1, 2, 3,4, 5, 6, 7, 8 or more times to the recurrent parent. The parental canolaplant that contributes the gene for the desired characteristic is termedthe nonrecurrent or donor parent. This terminology refers to the factthat the nonrecurrent parent is used one time in the backcross protocoland therefore does not recur. The parental canola plant to which thegene or genes from the nonrecurrent parent are transferred is known asthe recurrent parent as it is used for several rounds in thebackcrossing protocol (Poehlman & Sleper, 1994; Fehr, Principles ofCultivar Development (1987)). In a typical backcross protocol, theoriginal variety of interest (recurrent parent) is crossed to a secondvariety (nonrecurrent parent) that carries the single gene of interestto be transferred. The resulting progeny from this cross are thencrossed again to the recurrent parent and the process is repeated untila canola plant is obtained wherein essentially all of the desiredmorphological and physiological characteristics of the recurrent parentare recovered in the converted plant, in addition to the singletransferred gene from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single gene of the recurrent variety ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphological,constitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some agronomically important trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered to determine an appropriate testing protocol.Although backcrossing methods are simplified when the characteristicbeing transferred is a dominant allele, a recessive allele may also betransferred. In this instance it may be necessary to introduce a test ofthe progeny to determine if the desired characteristic has beensuccessfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new variety but that can beimproved by backcrossing techniques. Single gene traits may or may notbe transgenic; examples of these traits include but are not limited to,male sterility, waxy starch, herbicide tolerance, resistance forbacterial, fungal, or viral disease, insect resistance, male fertility,enhanced nutritional quality, industrial usage, yield stability andyield enhancement. These genes are generally inherited through thenucleus. Several of these single gene traits are described in U.S. Pat.Nos. 5,959,185; 5,973,234 and 5,977,445, each of which is incorporatedherein by reference in its entirety.

Introduction of a New Trait or Locus into SCV119103

Line SCV119103 represents a new base genetic variety into which a newlocus or trait may be introgressed. Direct transformation andbackcrossing represent two important methods that can be used toaccomplish such an introgression. The term backcross conversion andsingle locus conversion are used interchangeably to designate theproduct of a backcrossing program.

Backcross Conversions of SCV119103

A backcross conversion of SCV119103 occurs when DNA sequences areintroduced through backcrossing with SCV119103 utilized as the recurrentparent. Both naturally occurring and transgenic DNA sequences may beintroduced through backcrossing techniques. A backcross conversion mayproduce a plant with a trait or locus conversion in at least two or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, or at least 5 crosses. Molecular marker assisted breeding orselection may be utilized to reduce the number of backcrosses necessaryto achieve the backcross conversion. For example, see Openshaw, S. J.,et al., Marker-assisted Selection in Backcross Breeding. In: ProceedingsSymposium of the Analysis of Molecular Data, August 1994, Crop ScienceSociety of America, Corvallis, Oreg., where it is demonstrated that abackcross conversion can be made in as few as two backcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes as vs.unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear) and the types of parents includedin the cross. It is understood by those of ordinary skill in the artthat for single gene traits that are relatively easy to classify, thebackcross method is effective and relatively easy to manage (seeHallauer, et al. in Corn and Corn Improvement, Sprague and Dudley, ThirdEd. 1998). Desired traits that may be transferred through backcrossconversion include, but are not limited to, sterility (nuclear andcytoplasmic), fertility restoration, nutritional enhancements, droughttolerance, nitrogen utilization, altered fatty acid profile, alteredseed amino acid levels, altered seed oil levels, low phytate, industrialenhancements, disease resistance (bacterial, fungal or viral), insectresistance and herbicide tolerance. In addition, an introgression siteitself, such as an FRT site, Lox site or other site specific integrationsite, may be inserted by backcrossing and utilized for direct insertionof one or more genes of interest into a specific plant variety. In someembodiments of the invention, the number of loci that may be backcrossedinto SCV119103 is at least 1, 2, 3, 4, or 5 and/or no more than 6, 5, 4,3, or 2. A single locus may contain several transgenes, such as atransgene for disease resistance that, in the same expression vector,also contains a transgene for herbicide tolerance. The gene forherbicide tolerance may be used as a selectable marker and/or as aphenotypic trait. A single locus conversion of site specific integrationsystem allows for the integration of multiple genes at the convertedloci.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the gene(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withselection for the converted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman, Breeding Field Crops,P. 204 (1987). Poehlman suggests from one to four or more backcrosses,but as noted above, the number of backcrosses necessary can be reducedwith the use of molecular markers. Other factors, such as a geneticallysimilar donor parent, may also reduce the number of backcrossesnecessary. As noted by Poehlman, backcrossing is easiest for simplyinherited, dominant and easily recognized traits.

One process for adding or modifying a trait or locus in canola lineSCV119103 comprises crossing SCV119103 plants grown from SCV119103 seedwith plants of another canola variety that comprise the desired trait orlocus, selecting F₁ progeny plants that comprise the desired trait orlocus to produce selected F₁ progeny plants, crossing the selectedprogeny plants with the SCV119103 plants to produce backcross progenyplants, selecting for backcross progeny plants that have the desiredtrait or locus and the morphological characteristics of canola lineSCV119103 to produce selected backcross progeny plants; and backcrossingto SCV119103 three or more times in succession to produce selectedfourth or higher backcross progeny plants that comprise said trait orlocus. The modified SCV119103 may be further characterized as havingessentially all of the physiological and morphological characteristicsof canola line SCV119103 listed in Table 1 and/or may be characterizedby percent similarity or identity to SCV119103 as determined by SSRmarkers. The above method may be utilized with fewer backcrosses inappropriate situations, such as when the donor parent is highly relatedor markers are used in the selection step. Desired traits that may beused include those nucleic acids known in the art, some of which arelisted herein, that will affect traits through nucleic acid expressionor inhibition. Desired loci include the introgression of FRT, Lox andother sites for site specific integration, which may also affect adesired trait if a functional nucleic acid is inserted at theintegration site.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny canola seed byadding a step at the end of the process that comprises crossingSCV119103 with the introgressed trait or locus with a different canolaplant and harvesting the resultant first generation progeny canola seed.

Tissue Culture of Canola

Further production of the SCV119103 line can occur by tissue culture andregeneration. Tissue culture of various tissues of canola andregeneration of plants therefrom is known and widely published. Forexample, reference may be had to Chuong, et al., “A Simple CultureMethod for Brassica Hypocotyl Protoplasts”, Plant Cell Reports 4:4-6(1985); Barsby, T. L., et al., “A Rapid and Efficient AlternativeProcedure for the Regeneration of Plants from Hypocotyl Protoplasts ofBrassica napus”, Plant Cell Reports, (Spring, 1996); Kartha, K., et al.,“In vitro Plant Formation from Stem Explants of Rape”, Physiol. Plant,31:217-220 (1974); Narasimhulu, S., et al., “Species Specific ShootRegeneration Response of Cotyledonary Explants of Brassicas”, Plant CellReports, (Spring 1988); Swanson, E., “Microspore Culture in Brassica”,Methods in Molecular Biology, Vol. 6, Chapter 17, p. 159 (1990). Thus,another aspect of this invention is to provide cells which upon growthand differentiation produce canola plants having the physiological andmorphological characteristics of canola line SCV119103.

As used herein, the term “tissue culture” indicates a compositioncomprising isolated cells of the same or a different type or acollection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures are protoplasts, calli, plant clumps, and plantcells that can generate tissue culture that are intact in plants orparts of plants, such as embryos, pollen, flowers, seeds, pods, leaves,stems, roots, root tips, anthers, and pistils. Means for preparing andmaintaining plant tissue culture are well-known in the art. By way ofexample, a tissue culture comprising organs has been used to produceregenerated plants. U.S. Pat. Nos. 5,959,185, 5,973,234 and 5,977,445,describe certain techniques, each of which is incorporated herein byreference in its entirety.

Using SCV119103 to Develop other Canola Varieties

Canola varieties such as SCV119103 are typically developed for use inseed and grain production. However, canola varieties such as SCV119103also provide a source of breeding material that may be used to developnew canola varieties. Plant breeding techniques known in the art andused in a canola plant breeding program include, but are not limited to,recurrent selection, mass selection, bulk selection, mass selection,backcrossing, pedigree breeding, open pollination breeding, restrictionfragment length polymorphism enhanced selection, genetic marker enhancedselection, making double haploids, and transformation. Oftencombinations of these techniques are used. The development of canolavarieties in a plant breeding program requires, in general, thedevelopment and evaluation of homozygous varieties. For a generaldescription of rapeseed and canola breeding, see Downey, et al., 1987.Rapeseed and Mustard in Fehr, W. R. (ed.), Principles of CultivarDevelopment p. 437-486.

Farming Press Ltd., WharefedaleRoad, Ipswich, Suffolk.

Additional Breeding Methods

This invention, in an embodiment, is directed to methods for producing acanola plant by crossing a first parent canola plant with a secondparent canola plant wherein either the first or second parent canolaplant is line SCV119103. The other parent may be any other canola plant,such as a canola plant that is part of a synthetic or naturalpopulation. Any such methods using canola line SCV119103 are part ofthis invention: selfing, sibbing, backcrosses, mass selection, pedigreebreeding, bulk selection, hybrid production, or crosses to populations.These methods are well-known in the art and some of the more commonlyused breeding methods are described below. Descriptions of breedingmethods can be found in one of several reference books (e.g., Allard,Principles of Plant Breeding, 1960; Simmonds, Principles of CropImprovement, 1979; Sneep, et al., 1979).

The following describes breeding methods that may be used with canolaline SCV119103 in the development of further canola plants. One suchembodiment is a method for developing a line SCV119103 progeny canolaplant in a canola plant breeding program comprising: obtaining thecanola plant, or a part thereof, of line SCV119103 utilizing said plantor plant part as a source of breeding material and selecting a canolaline SCV119103 progeny plant with molecular markers in common with lineSCV119103 and/or with morphological and/or physiological characteristicsselected from the characteristics listed in Table 1. Breeding steps thatmay be used in the canola plant breeding program include pedigreebreeding, backcrossing, mutation breeding, and recurrent selection. Inconjunction with these steps, techniques such as RFLP-enhancedselection, genetic marker enhanced selection (for example SSR markers)and the making of double haploids may be utilized.

Another method involves producing a population of canola line SCV119103progeny canola plants, comprising crossing line SCV119103 with anothercanola plant, thereby producing a population of canola plants, which, onaverage, derive 50% of their alleles from canola line SCV119103. A plantof this population may be selected and repeatedly selfed or sibbed witha canola line resulting from these successive filial generations. Oneembodiment of this invention is the canola line produced by this methodand that has obtained at least 50% of its alleles from canola lineSCV119103.

One of ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see Fehr and Walt, Principles of CultivarDevelopment, p 261-286 (1987). Thus, the invention includes, in anembodiment, canola line SCV119103 progeny canola plants comprising acombination of at least two line SCV119103 traits selected from thegroup consisting of those listed in Table 1. In anther embodiment, theline SCV119103 comprises any combination of traits described herein. Ineither embodiment, the progeny canola plant may not be significantlydifferent for said traits than canola line SCV119103 as determined atthe 5% significance level when grown in the same environmentalconditions. Using techniques described herein, molecular markers may beused to identify said progeny plant as a canola line SCV119103 progenyplant. Mean trait values may be used to determine whether traitdifferences are significant, and the traits may then be measured onplants grown under the same environmental conditions. Once such avariety is developed its value is substantial since it is important toadvance the germplasm base as a whole in order to maintain or improvetraits such as yield, disease resistance, pest resistance, and plantperformance in extreme environmental conditions.

Progeny of canola line SCV119103 may also be characterized through theirfilial relationship with canola line SCV119103, as for example, beingwithin a certain number of breeding crosses of canola line SCV119103. Abreeding cross is a cross made to introduce new genetics into theprogeny, and is distinguished from a cross, such as a self or a sibcross, made to select among existing genetic alleles. The lower thenumber of breeding crosses in the pedigree, the closer the relationshipbetween canola line SCV119103 and its progeny. For example, progenyproduced by the methods described herein may be within 1, 2, 3, 4 or 5breeding crosses of canola line SCV119103.

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such asSCV119103 and another canola variety having one or more desirablecharacteristics that is lacking or which complements SCV119103. If thetwo original parents do not provide all the desired characteristics,other sources can be included in the breeding population. In thepedigree method, superior plants are selfed and selected in successivefilial generations. In the succeeding filial generations theheterozygous condition gives way to homogeneous varieties as a result ofself-pollination and selection. Typically in the pedigree method ofbreeding, five or more successive filial generations of selfing andselection is practiced: F₁ to F₂; F₂ to F₃; F₃ to F₄; F₄ to F₅, etc.After a sufficient amount of inbreeding, successive filial generationswill serve to increase seed of the developed variety. The developedvariety may comprise homozygous alleles at about 95% or more of itsloci.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety, the donor parent, to adeveloped variety called the recurrent parent, which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent but at the same time retain manycomponents of the non-recurrent parent by stopping the backcrossing atan early stage and proceeding with selfing and selection. For example, acanola variety may be crossed with another variety to produce a firstgeneration progeny plant. The first generation progeny plant may then bebackcrossed to one of its parent varieties to create a BC1 or BC2.Progeny are selfed and selected so that the newly developed variety hasmany of the attributes of the recurrent parent and yet several of thedesired attributes of the non-recurrent parent. This approach leveragesthe value and strengths of the recurrent parent for use in new canolavarieties.

Therefore, an embodiment of this invention is a method of making abackcross conversion of canola line SCV119103, comprising the steps ofcrossing a plant of canola line SCV119103 with a donor plant comprisinga desired trait, selecting an F₁ progeny plant comprising the desiredtrait, and backcrossing the selected F₁ progeny plant to a plant ofcanola line SCV119103. This method may further comprise the step ofobtaining a molecular marker profile of canola line SCV119103 and usingthe molecular marker profile to select for a progeny plant with thedesired trait and the molecular marker profile of SCV119103. In oneembodiment, the desired trait is a mutant gene or transgene present inthe donor parent.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. SCV119103 is suitable for use in arecurrent selection program. The method entails individual plants crosspollinating with each other to form progeny. The progeny are grown andthe superior progeny selected by any number of selection methods, whichinclude individual plant, half-sib progeny, full-sib progeny and selfedprogeny. The selected progeny are cross pollinated with each other toform progeny for another population. This population is planted andagain superior plants are selected to cross pollinate with each other.Recurrent selection is a cyclical process and therefore can be repeatedas many times as desired. The objective of recurrent selection is toimprove the traits of a population. The improved population can then beused as a source of breeding material to obtain new varieties forcommercial or breeding use, including the production of a syntheticline. A synthetic line is the resultant progeny formed by theintercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self pollination, directed pollinationcould be used as part of the breeding program.

Mutation Breeding

Mutation breeding is another method of introducing new traits intocanola line SCV119103. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (from 2500 to 2900 nm), or chemical mutagens (such as baseanalogues (5-bromo-uracil), related compounds (8-ethoxy caffeine),antibiotics (streptonigrin), alkylating agents (sulfur mustards,nitrogen mustards, epoxides, ethylenamines, sulfates, sulfonates,sulfones, lactones), azide, hydroxylamine, nitrous acid, or acridines.Once a desired trait is observed through mutagenesis the trait may thenbe incorporated into existing germplasm by traditional breedingtechniques. Details of mutation breeding can be found in Fehr, 1993.Principles of Cultivar Development, Macmillan Publishing Company. Inaddition, mutations created in other canola plants may be used toproduce a backcross conversion of canola line SCV119103 that comprisessuch mutation.

Breeding with Molecular Markers

Molecular markers, which include markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs) and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing canola line SCV119103. One use of molecularmarkers is QTL mapping. QTL mapping is the use of markers, which areknown to be closely linked to alleles that have measurable effects on aquantitative trait. Selection in the breeding process is based upon theaccumulation of markers linked to the positive effecting alleles and/orthe elimination of the markers linked to the negative effecting allelesfrom the plant's genome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.Molecular markers may also be used to identify and exclude certainsources of germplasm as parental varieties or ancestors of a plant byproviding a means of tracking genetic profiles through crosses.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a canola plant for which canola line SCV119103 is a parent canbe used to produce double haploid plants. Double haploids are producedby the doubling of a set of chromosomes (1 N) from a heterozygous plantto produce a completely homozygous individual. For example, see Wan, etal., (1989) “Efficient Production of Doubled Haploid Plants ThroughColchicine Treatment of Anther-Derived Maize Callus”, Theor. Appl.Genet., 77:889-892 and U.S. Pat. No. 7,135,615, incorporated herein byreference in its entirety. This can be advantageous because the processomits the generations of selfing needed to obtain a homozygous plantfrom a heterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. Methods for obtaining haploidplants are also disclosed in Kobayashi, M., et al., J. Heredity71(1):9-14, 1980, Pollacsek, M., Agronomie (Paris) 12(3):247-251, 1992;Cho-Un-Haing, et al., J Plant Biol., 1996, 39(3):185-188; Verdoodt, L.,et al., February 1998, 96(2):294-300; Genetic Manipulation in PlantBreeding, Proceedings International Symposium Organized by EUCARPIA,Sep. 8-13, 1985, Berlin, Germany; Chalyk, et al., 1994, Maize GenetCoop. Newsletter 68:47; Chalyk, S.

Thus, an embodiment of this invention is a process for making asubstantially homozygous SCV119103 progeny plant by producing orobtaining a seed from the cross of SCV119103 and another canola plantand applying double haploid methods to the F₁ seed or F₁ plant or to anysuccessive filial generation. Based on studies in maize and currentlybeing conducted in canola, such methods would decrease the number ofgenerations required to produce a variety with similar genetics orcharacteristics to SCV119103. See Bernardo, R. and Kahler, A. L., Theor.Appl. Genet. 102:986-992, 2001.

In particular, a process of making seed retaining the molecular markerprofile of canola line SCV119103 is contemplated, such processcomprising obtaining or producing F₁ seed for which canola lineSCV119103 is a parent, inducing doubled haploids to create progenywithout the occurrence of meiotic segregation, obtaining the molecularmarker profile of canola line SCV119103, and selecting progeny thatretain the molecular marker profile of SCV119103.

A pollination control system and effective transfer of pollen from oneparent to the other offers improved plant breeding and an effectivemethod for producing hybrid canola seed and plants. For example, theogura cytoplasmic male sterility (cms) system, developed via protoplastfusion between radish (Raphanus sativus) and rapeseed (Brassica napus)is one of the most frequently used methods of hybrid production. Itprovides stable expression of the male sterility trait (Ogura 1968),Pelletier, et al. (1983) and an effective nuclear restorer gene (Heyn1976).

In developing improved new Brassica hybrid varieties, breeders useself-incompatible (SI), cytoplasmic male sterile (CMS) and nuclear malesterile (NMS) Brassica plants as the female parent. In using theseplants, breeders are attempting to improve the efficiency of seedproduction and the quality of the F₁ hybrids and to reduce the breedingcosts. When hybridization is conducted without using SI, CMS or NMSplants, it is more difficult to obtain and isolate the desired traits inthe progeny (F₁ generation) because the parents are capable ofundergoing both cross-pollination and self-pollination. If one of theparents is a SI, CMS or NMS plant that is incapable of producing pollen,only cross pollination will occur. By eliminating the pollen of oneparental variety in a cross, a plant breeder is assured of obtaininghybrid seed of uniform quality, provided that the parents are of uniformquality and the breeder conducts a single cross.

In one instance, production of F₁ hybrids includes crossing a CMSBrassica female parent, with a pollen producing male Brassica parent. Toreproduce effectively, however, the male parent of the F₁ hybrid musthave a fertility restorer gene (Rf gene). The presence of an Rf genemeans that the F₁ generation will not be completely or partiallysterile, so that either self-pollination or cross pollination may occur.Self pollination of the F₁ generation to produce several subsequentgenerations is important to ensure that a desired trait is heritable andstable and that a new variety has been isolated.

An example of a Brassica plant which is cytoplasmic male sterile andused for breeding is ogura (OGU) cytoplasmic male sterile (R.Pellan-Delourme, et al., 1987). A fertility restorer for oguracytoplasmic male sterile plants has been transferred from Raphanussativus (radish) to Brassica by Instit. National de Recherche Agricole(INRA) in Rennes, France (Pelletier, et al., 1987). The restorer gene,Rf1 originating from radish, is described in WO 92/05251 and inDelourme, et al., (1991). Improved versions of this restorer have beendeveloped. For example, see WO 98/27806 “Oilseed brassica containing animproved fertility restorer gene for ogura cytoplasmic male sterility”.

Other sources and refinements of CMS sterility in canola include thePolima cytoplasmic male sterile plant, as well as those of U.S. Pat. No.5,789,566, “DNA sequence imparting cytoplasmic male sterility,mitochondrial genome, nuclear genome, mitochondria and plant containingsaid sequence and process for the preparation of hybrids”; U.S. Pat. No.5,973,233 “Cytoplasmic male sterility system production canola hybrids”;and WO 97/02737 “Cytoplasmic male sterility system producing canolahybrids”; EP patent application 0 599042A “Methods for introducing afertility restorer gene and for producing F₁ hybrids of Brassica plantsthereby”; U.S. Pat. No. 6,229,072 “Cytoplasmic male sterility systemproduction canola hybrids”; U.S. Pat. No. 4,658,085 “Hybridization usingcytoplasmic male sterility, cytoplasmic herbicide tolerance, andherbicide tolerance from nuclear genes”; each of which is incorporatedherein by reference in its entirety.

Further, as a result of the advances in sterility systems, lines aredeveloped that can be used as an open pollinated variety (i.e. apureline line sold to the grower for planting) and/or as a sterileinbred (female) used in the production of Ft hybrid seed. In the lattercase, favorable combining ability with a restorer (male) would bedesirable. The resulting hybrid seed would then be sold to the growerfor planting.

The development of a canola hybrid in a canola plant breeding programinvolves three steps: (1) the selection of plants from various germplasmpools for initial breeding crosses; (2) the selfing of the selectedplants from the breeding crosses for several generations to produce aseries of inbred lines, which, although different from each other, breedtrue and are highly uniform; and (3) crossing the selected inbred lineswith different inbred lines to produce the hybrids. During theinbreeding process in canola, the vigor of the lines decreases. Vigor isrestored when two different inbred lines are crossed to produce thehybrid. An important consequence of the homozygosity and homogeneity ofthe inbred lines is that the hybrid between a defined pair of inbredswill always be the same. Once the inbreds that give a superior hybridhave been identified, the hybrid seed can be reproduced indefinitely aslong as the homogeneity of the inbred parents is maintained.

Combining ability of a line, as well as the performance of the line, isa factor in the selection of improved canola lines that may be used asinbreds. Combining ability refers to a line's contribution as a parentwhen crossed with other lines to form hybrids. The hybrids formed forthe purpose of selecting superior lines are designated test crosses. Oneway of measuring combining ability is by using breeding values. Breedingvalues are based on the overall mean of a number of test crosses. Thismean is then adjusted to remove environmental effects and it is adjustedfor known genetic relationships among the lines.

Hybrid seed production requires inactivation of pollen produced by thefemale parent. Incomplete inactivation of the pollen provides thepotential for self-pollination. This inadvertently self-pollinated seedmay be unintentionally harvested and packaged with hybrid seed.Similarly, because the male parent is grown next to the female parent inthe field there is also the potential that the male selfed seed could beunintentionally harvested and packaged with the hybrid seed. Once theseed from the hybrid bag is planted, it is possible to identify andselect these self-pollinated plants. These self-pollinated plants willbe genetically equivalent to one of the inbred lines used to produce thehybrid. Though the possibility of inbreds being included in hybrid seedbags exists, the occurrence is rare because much care is taken to avoidsuch inclusions. These self-pollinated plants can be identified andselected by one skilled in the art, either through visual or molecularmethods.

Brassica napus canola plants, absent the use of sterility systems, arerecognized to commonly be self-fertile with approximately 70 to 90percent of the seed normally forming as the result of self-pollination.The percentage of cross pollination may be further enhanced whenpopulations of recognized insect pollinators at a given growing site aregreater. Thus open pollination is often used in commercial canolaproduction.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard, 1960; Simmonds, 1979; Sneep, et al., 1979; Fehr,1987).

Industrial Uses

Currently Brassica napus canola is recognized as an increasinglyimportant oilseed crop and a source of meal in many parts of the world.The oil as removed from the seeds commonly contains a lesserconcentration of endogenously formed saturated fatty acids than othervegetable oils and is well suited for use in the production of salad oilor other food products or in cooking or frying applications. The oilalso finds utility in industrial applications. Additionally, the mealcomponent of the seeds can be used as a nutritious protein concentratefor livestock.

Canola oil has the lowest level of saturated fatty acids of allvegetable oils. “Canola” refers to rapeseed (Brassica) which has aerucic acid (C221) content of at most 2 percent by weight based on thetotal fatty acid content of a seed, and which produces, after crushing,an air-dried meal containing less than 30 micromoles (μmol) per gram ofdefatted (oil-free) meal. These types of rapeseed are distinguished bytheir edibility in comparison to more traditional varieties of thespecies.

Canola line SCV119103 can be used in the production of an ediblevegetable oil or other food products in accordance with knowntechniques. The solid meal component derived from seeds can be used as anutritious livestock feed. Parts of the plant not used for human oranimal food can be used for biofuel.
